对某TATB基高聚粘结炸药(PBX)进行了55~75 ℃加速老化试验,并对老化前后的样品进行了不同温度下压缩性能、拉伸性能和弯曲蠕变实验,用扫描电子显微镜对老化前后炸药高温拉伸断口形貌进行了观察.结果表明: 长期高温贮存后,TATB基高聚物粘结炸药晶体与粘合剂仍具有良好的粘合界面,其模量、破坏强度、破坏应变和稳态蠕变速率等力学性能指标均未发生明显的变化.

The accelerated thermal aging tests of PBX based on TATB were carried out by using a hot air oven from 55 ℃ to 75 ℃. The mechanical properties such as tensile strength,elongation at failure and modulus were measured before and after aging. Morphology of rapture section from tensile test at 55 ℃ was observed by using scanning electric microscopy(SEM). Results show that the mechanical properties and the interfacial mechanism between binder and TATB crystal do not undergo changes significant during the aging period.
